4.1 Safety instructions for the installation
4.2 Preparation
•
Prior to installation, ensure that the O-ring at the connecting flange is seated properly.
•
There must be no foreign objects in the oil infeed or outfeed area of the Ölspiegelregulators.
•
The device has to be mounted to the compressor horizontally. It can be rotated by 180°.
•
Use matching washers for the flange fastening screws.
•
For use at low temperatures, an oil sump heater has to be installed, to ensure trouble-free operation of the
Ölspiegelregulators.
•
An oil filter has to be installed in the oil infeed line of the Ölspiegelregulators, to prevent the solenoid valve seat
from getting dirty.
4.3 Electrical connection
•
The electrical connection is carried out according to the respective wiring diagrams, which are part of the
corresponding data sheets.
•
For the 115V and 24V versions, ensure that the correct supply voltage is used.
Danger of bursting
• Pressurised parts that burst can cause serious to fatal injuries.
 The max. test pressure must not be exceeded.
Pressure in the compressor
• Working on pressurised parts can cause serious to fatal injuries.
 Work on the pneumatic equipment may only be carried out by refrigeration technicians.
 Depressurise the respective part of the system before installation or disassembly.
Electric shock
• Touching live parts can lead to serious to fatal injuries.
 Work on the electric equipment may only be carried out by electricians, taking into account
the information specified in the Technical specifications chapter.
 The applicable European and national standards for connecting electrical equipment must
be observed.
 The voltage supply to the oil level regulator has to be switched off prior to connection/
installation and the subsequent tasks.
 Maintain the operating voltage specified on type plate.
Soiling of the oil level regulator, in particular the oil connections.
• Soiling can cause malfunctions.
 Installation must be carried out without soiling.
Separate isolation switches are necessary for the KRIWAN oil level regulators.
